Abstract
The present invention relates to filled polymeric materials including a polymer and a mass of metallic fibers distributed within the polymer, and to light weight composites which comprise at least a pair of metallic layers and a polymeric layer interposed between the pair of metallic layers, the polymeric layer containing the filled polymeric material. The composite materials of the present invention may be formed using conventional stamping equipment at ambient temperatures. Composite materials of the present invention may also be capable of being welded to other metal materials using a resistance welding process such as resistance spot welding. Preferred composite materials include one or any combination of the following features: metallic fibers that are ribbon fibers; a polymer selected from a polyolefin, a polyamide, or a combination thereof; or a metallic layer (e.g., one or both of the pair of metallic layers) having a surface facing the filled polymeric material that is untreated.
